AUTOMOBILE-HEATER.

Specification of Letters Patent. Patented NOV, 12, 1918.

Application led March 31, 1917. Serial No. 158,797.

To all whom t may concern:

Be it known that I, JOSEPH B. FRANCISCO, a citizen of the United States, residing at Columbus, inthe county of Franklin and State of Ohio, have invented certain new and useful Improvements in Automobile-Heaters, of which the following is a specification.

This invention relates to automobile heaters and is designed for the double purpose of heating theinterior of the vehicle and also heating the gasolene as it is fed to the carbureter.

In view of the foregoing, the main` object of my invention resides in the combination with a vacuum tank ordinarily used in connection with gasolene feed systems for automobiles, of a heating jacket arranged to heat A the contents of the tank by passage of air be utilized to heat the interior ofthe car should this be desired or, it may be caused to pass off into the external atmosphere.

My invention also resides in combining a jacket with both the intake and exhaust manifolds, which jacket is Openat its forward end and also at its rear end to admit heated air to the interior of the vehicle. This heated air also has the function of heating the intake manifold in its. passage rearwardly. In this connection, I have also resorted to the use ofa damper structure for tempering or regulatin the temperature of the air within the jac et surrounding the two manifolds. l

The preferred embodiment of my inven= tion is shown in the accompanying sheet of drawings, in which similar characters of reference designate corresponding parts, and in' which:

Figure 1 shows my invention applied to the vehicle and its engine, represented diagrammatically,

Fig.- 2 is an -enlarged section taken on line 2 2 of Fig. i,

Fig. 3 is an enlarged view showing the detail construction of the exhaust pipe and jacketv and also the register leading to the interior` of the car,

Fig. 4 is a cross section of the exhaust manifold andja'cket shown in Fig. 3, and,

Fig. 5 is an enlarged view of the forward end 0f the jacket, showing the closing plate in an open position.

In Fig. 1, the carbureter 1 is shown diagrammatically and may be of any conven tional type, this carbureter operating in conjunction with the internal combustion engine represented in. dotted lines at 2. As is customary in most automobiles, a vacuum tank 3 is located on the outside of the dash 4, the purpose of this vacuum tank being to feed gasolene to the carbureter caused by the vacuum created by the operation of the engine. The carbureter 1 is shown as communicating with the intake manifold 5 through the medium of a short connection 6 and this intake manifold is located directly below the exhaust manifold 7 connected to an exhaust pipe 8 leading rearwardly to the rearofthe vehicle. It is my purpose t0 inclose or jacket the two manifolds by means of the jacket 9, which latter is open at its front end 10 and provided with a line wire screen 31, but this opening is in turn controlled 'by means o,f the hinged door 11, which latter may be operated fromthe seat of the vehicle through the medium of the cord 12. The rear end of this jacket 9 leads into the interior 'of the car, as is shown at 13 and this openin is also controlled by means of a pivoted amper door 14 operated by means of the handle shown at 15. By the arrangement thus far described, the` heat radiated by the exhaust manifold 7 in tur-n heats the air passing through the jacket 9 and in this manner both the incoming gases to the engine and the interior of the vehicle are heated. The amount of air passing through the jacket may be regulated by adjusting the door 11 and the amount of air entering the vehicle, may in turn be regulated by adjusting the damper 14. To further temper the air within the jacket 9, I

, have provided an adjustable slide 16 m'ounted in guides 17 located within the top of the 'jacket 9 as is shown in Figs. 1 and 2. This vvlation of cold air through the jacket from the front opening 10 out through the opening caused b v the slide 16.

The feed pipe 18 leading from the vacuum tank 'to the carburetel 1 is also preferably caused to encircle the exhaust manifold as is shown in Fig. 1 and to do this, it is necessary that it pass through the jacket 9, which latter is preferably formed integral with grasolene.

ln order that the njasoiene may to some extent, het'ore it passes tl onoh the connecting pipe lo, so as to nini: tain the uniform consistencj1 of the entire quinntijY within the vacuum tank, l have jacketcd this vacuum tank. as is shown at 20. pipe 2i leading from the jacket t) connects with the Space it'ormed hetiveen the vacuum tank and the jacket 2() and in this` manner the pas@ lelie contined within the tank is also heated.

damper shown at 22 may he used to regulate tl l amount ot air passing through the pipe 21. in order that the air passing about the jacket 2O may he utilized to heat the ijn terior ot the vehicle7 l have also provided a pipe 23 leading from the jacket 2l to the interior ot the vehicle, this pipe lacing provided *with a removable cap i2-i. 'ilo the opposite side of the vacuum tank jacket.y there is also provided an outlet pipe 25, which carries a cap 26 at. its outer end. The purpose` of these two pipes 23 and is to lead the heated air either to the interior ot the vehicle or into the exterio' atmosphere, as majv he desired. lf it is desired to admit this heated air to the interior oitl the vehicle, the damper cap 26 iS placed in a closed position over the pipe and the pipe 23 opened into the interior of the car. Should the reverse he true, the cap 21st is placed in a closed position over the pipe :23 and the pipe Q5 opened to permit the heated air passing from the jacket 9 through the jacket 2() into the exterior atmosphere.

In multi-seated vehicles. it is also desirable to heat the rear portion of the same and t0 thisI end. l have integrally formed with the exhaust pipe ing jacket 2T which terminates in a register structure 28 at its rear end, this latter having an opening 29 and a ree'nlatinfr door 30.

8 an additional heati il hifi the door 30 is in the position shown in .il the heated air into the interic` et the vehicle, lont should it loe moved throngg'li ninety7 degrees, the heated air passes ian-h the openingI Fiom, the Jlio-reescription, it iviil he apparent that il a constriictionhavingconjv .vvherein the. gasolene convacmnn tank ispre-heatel is heate hy its circulation aiiou e ausi; mainte-id. A in addition to this, air thus utilised mayv be tnrther utiiifJ ,ci heat, the interior ot the vehicie. llista the jacket surrounding the intake and exhaust manifold is constructed so that the interior of the vehicle majv he additionally heated and the air passing through this jacket also tempered either by regulating the door ll er the slide lo.

it is ohvions that the employment. of the sereen 3l, will prevent the ent ance of dirt or other undesirable matter to the jacket.
